Abstract
Background: In recent years, amphetamine-type-stimulants (ATS) have been extensively misused in South-East Asia, inducing major problems among methadone-maintenance-treatment (MMT) patients.Objective: We examine ATS-misuse prevalence and its determinants among MMT patients in East-Coast-Malaysia.Methods: A retrospective-observational study was conducted on government-subsidized medication for opioid-use-disorder (MOUD) treatment clinics involving 292 MMT-patients (98% males) who were selected using a multilevel-proportional-stratified random sampling technique. Information obtained during the mandatory monitoring procedure from January 1 to December 31 2019, was utilized to determine ATS misuse prevalence from consecutive random urine drug screening. The determinants associated with its use, namely sociodemographics, social networks, comorbidities, and pharmacological assessments were analyzed via a logistic model.Results: Overall, 52.2% of the MMT-patients (95% CI: 0.42-0.54) had misused ATS at least once during their methadone treatment. These misusing patients were active smokers, hepatitis B and C seronegative, concurrently misused opioids, and had received suboptimum prescribed doses of methadone. Multiple logistic regression analysis demonstrated that the odds of misusing ATS during methadone treatment were 37 times higher among those who concurrently misused opioids (AOR: 37.60, 95% CI: 14.03-100.74) and 12 times higher among those who received suboptimal methadone doses (<60 mg/day) (AOR: 12.24, 95% CI: 5.58-25.43).Conclusion: This study demonstrated the significant prevalence of ATS misuse among MMT-patients in East-Coast-Malaysia, especially among patients who were prescribed suboptimal doses of methadone and/or demonstrated concomitant opioid-misuse. Stringent urine-monitoring is crucial to prevent diversion to ATS misuse. Nonetheless, to avoid negligence and improve physician engagement, the relevant authorities should immediately plan a comprehensive national-standard training module comprising support activities for professional methadone-prescribers.

Patterns of and Rationale for the Co-use of Methamphetamine and Opioids: Findings From Qualitative Interviews in New Mexico and Nevada. Front Psychiatry 2022; 13:824940. [PMID: 35418887 PMCID: PMC8995976 DOI: 10.3389/fpsyt.2022.824940] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/30/2021] [Accepted: 03/01/2022] [Indexed: 11/13/2022] Open
Abstract
Introduction Methamphetamine use and methamphetamine-involved deaths have increased dramatically since 2015, and opioid-related deaths now frequently involve methamphetamine. Nevada and New Mexico are states with elevated rates of opioid and methamphetamine use. In this paper, we report results from a qualitative analysis that examined patterns of methamphetamine and opioid co-use over participants' lifespan, factors that influence those patterns, and implications for health outcomes among users. Methods Project AMPED was a multisite, mixed-methods study of methamphetamine use in Northern New Mexico and Northern Nevada. Between December 2019 and May 2020, qualitative interview participants were asked to describe their patterns of and reasons for co-administration of opioids and methamphetamine. Results We interviewed 21 people who reported using methamphetamine in the past 3 months. Four primary patterns of methamphetamine and opioid co-use were identified: [1] using both methamphetamine and heroin, either simultaneously or sequentially (n = 12), [2] using methamphetamine along with methadone (n = 4), [3] using prescription opioids and methamphetamine (n = 1), and [4] using only methamphetamine (n = 4). Among those who used methamphetamine and heroin simultaneously or sequentially, motivations drew from a desire to enhance the effect of one drug or another, to feel the "up and down" of the "perfect ratio" of a goofball, or to mitigate unwanted effects of one or the other. Among those who used methamphetamine and methadone, motivations focused on alleviating the sedative effects of methadone. Conclusion To address the emergent trend of increasing methamphetamine-related deaths, researchers, health care professionals, and community health workers must acknowledge the decision-making processes behind co-use of opioids and methamphetamine, including the perceived benefits and harms of co-use. There is an urgent need to address underlying issues associated with drug use-related harms, and to design interventions and models of treatment that holistically address participants' concerns.

Abstract
The objective of this study was to determine the prevalence of amphetamine-type stimulant use and associated factors among methadone maintenance treatment (MMT) patients. In 2018, a cross-sectional study was conducted on 967 MMT patients at two methadone clinics in Ho Chi Minh City that serve Vietnamese patients. Amphetamine-type stimulant use was assessed by rapid urine test and face-to-face interview using the Alcohol, Smoking, Substance Involvement Screening Test (ASSIST) tool. The prevalence of amphetamine-type stimulant use assessed by urine test was 25.4%. According to ASSIST, the prevalence of moderate and high risk amphetamine-type stimulant use was 15.5% and 1.1%, respectively. Amphetamine-type stimulant use and hazardous use were more prevalent in younger patients, having a part-time job, drug injection, having a lower score of self-health assessment, treated with a higher dose of methadone and missing methadone dose in the past 3 months. By contrast, patients who were HIV positive were less likely to use amphetamine-type stimulants. Cannabis and heroin use were significantly associated with amphetamine-type stimulant use (OR = 1.46; 95% CI: 1.38-8.67; and OR = 1.50; CI: 1.04-2.18, respectively) and hazardous use (OR = 4.07; CI: 1.67-9.92; and OR = 2.38; CI: 1.56-3.63, respectively). Screening and interventions are needed to cope with this issue on time, particularly in young patients, having drug injection and concurrent drugs user groups.

Abstract
Background: Sociodemographic factors have an impact worldwide on the behavior of people who use drugs (PWUD). This study attempts to clarify the sociodemographic factors related to HIV/HCV high-risk behaviors (injection drug use, syringe sharing, and multiple sex partners) among PWUD on methadone maintenance treatment (MMT) in the long term. Methods: The 13,300 PWUD recruited into the MMT program were followed during 2006-2015. Generalized estimating equations were used to examine the relationship between sociodemographic characteristics and HIV/HCV high-risk behaviors. Results: We found that male (vs. female), living alone (vs. living with family or relatives), temporary income, financial support from family/friends, and financial support from social welfare (vs. regular salary) were positively associated with injection drug use. Age of initial drug use was negatively associated with injection drug use and syringe sharing. For both genders, being unmarried (vs. married or in cohabitation), living with friends, living alone (vs. living with family or relatives), temporary income, financial supports from family/friends (vs. regular salary), being employed (vs. unemployed/between jobs) was positively associated. In contrast, age at baseline was negatively associated with having multiple sexual partners for both genders. Ethnic of non-Han (vs. Han) was positively associated with having multiple sexual partners simply for males. Being divorced or widowed (vs. married or cohabitated) was positively associated with having multiple sexual partners merely for females. Conclusion: HIV/HCV high-risk behaviors correlated with certain sociodemographic factors of PWUD receiving MMT. There is a need for improving the well-being, employment, and housing status of PWUD on MMT to reduce their HIV/HCV risk behaviors.

Abstract
OBJECTIVES We explored the long-term immunogenicity induced by 60 μg and 20 μg hepatitis B vaccines among patients receiving methadone maintenance treatment (MMT). METHODS In initial study, a randomized controlled trial was conducted, in which patients receiving MMT were administered 20 µg (IM20 group) or 60 µg (IM60 group) hepatitis B vaccines at months 0, 1, and 6. In this study, the responders at month 7 were followed-up at months 18, 30, and 42 to estimate long-term immunogenicity. RESULTS The response rate decreased from 78.0% (39/50) to 31.1% (14/45) in the IM20 group, and from 86.0% (43/50) to 50.0% (20/40) in the IM60 group from month 7 to 42. Vaccine-induced responses in 75% of patients were observed for 14.2 months in the IM20 group and for 20.0 months in the IM60 group, and differences between these two groups were non-significant (P > 0.05). CONCLUSION The three-dose 20 µg and 60 µg hepatitis B vaccines showed similar rapid hepatitis B surface antibody decreases.

Changes in Substance Abuse and HIV Risk Behaviors over 12-Month Methadone Maintenance Treatment among Vietnamese Patients in Mountainous Provinces. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2019; 16:ijerph16132422.

Abstract
Methadone maintenance treatment (MMT) programs have been used worldwide to reduce the number of drug users and for HIV prevention; however, evidence of their effectiveness in mountainous areas is limited. This study aimed to identify changes in substance abuse and sexual practices among MMT patients after treatment in three Vietnamese mountainous provinces. A survey on risk behaviors was conducted among 300 drug users in six MMT clinics prior to and following one year of MMT. Cramér's effect size of changes was extrapolated to justify the magnitude of the intervention's effectiveness. A generalized estimation equation was used to find the factors associated with respondents' substance use and sexual risk behavior. While drug-related risk behaviors were significantly reduced, alcohol and sex-related behaviors remained risk factors for HIV in this group. Additionally, condom use was common among participants at both time points, but not among those having sex with sex workers. Socio-economic characteristics of ethnic, education, occupation, as well as drug use history influenced the possibility of engaging in drug use and/or sexual risk behavior following treatment. Further emphasis on managing these among MMT patients is required, potentially by providing integrated services including smoking and drinking counseling and condom use promotion in accordance with MMT.

Abstract
In Cambodia, HIV prevalence at 4% remains high among people who use drugs (PWUD). Complex and overlapping risk behaviors may enhance sexual transmission risk beyond PWUD. This study, therefore, aims to assess the factors associated with sexual risk behaviors among PWUD. Respondent Driven Sampling was used to recruit 1626 PWUD. Univariate and multivariate logistic regression analyses were used to identify factors associated with transmission risk including that high mental disorder scores were a strong predictor of sexual risk behaviors (odds ratio [OR] ranged from 1.9 to 2.8). Factors associated with sexual risk behaviors varied by gender: for men, these included geographical regions, non-married status, and heroin use; and for women, factors were age ≤20 years (OR = 5.4), living with friends (OR = 6.4), living in Central coastal region (OR = 6.1), and heroin use (OR = 4.8).

Abstract
A significant portion of the various communities, especially developing countries, is involved in drug abuse and receive formal drug treatments. Although the benefits of available therapeutics such as methadone maintenance treatment (MMT) for controlling infectious diseases have been confirmed, treatment failure has been seen in a large range of the patients. This review addresses the importance of a less attentive behavioural approach in reducing treatment withdrawal. The executive protocol, the outcomes and challenges, and the benefits of this approach are debatable.

Abstract
AIMS To examine drug use behavior of clients attending Methadone Maintenance Treatment (MMT) programs and its relationship with the clients' social network characteristics. DESIGN Cross-sectional study. SETTING Four MMT clinics in Kunming, Yunnan province, China. PARTICIPANTS 324 consecutive MMT clients. MEASUREMENTS A structured, self-completed questionnaire on background characteristics and existing social network. Current drug use was assessed by urine test for opiate metabolites. ANALYSIS The association between client's social network characteristics and their own current drug use behavior is analysed using multiple logistic regression adjusting for socio-demographic characteristics. Adjusted odds ratios (AOR) with 95% confidence intervals (CI) are obtained to give the strength of the associations. FINDINGS MMT clients were more likely to concurrently use heroin while attending MMT if their social network had any of the following characteristics: more than half of the members were older than them (AOR = 1.03, 95% CI = 1.00,1.06), any member had a high level of influence on them (AOR = 6.47, 95% CI = 2.86,14.65) and any member joined them in using drugs (AOR = 1.94, 95% CI = 1.04,3.63). Having a social network member who could provide emotional support (AOR = 0.11, 95% CI = 0.03,0.35), having a spouse and/or child in their social network (AOR = 0.44, 95% CI = 0.24,0.81) and having a social network member with a high level of closeness (AOR = 0.28, 95% CI = 0.09,0.90) were associated with a decreased odds of heroin use. CONCLUSION Social networks who could provide MMT clients with emotional support and a close relationship were significant factors for reducing the risk of concurrent drug use among clients attending MMT clinics in Kunming, China. Behavioral interventions should address the role of family and social network members in providing support to these clients.

Abstract
Ongoing drug use during opioid agonist treatment (OAT) negatively affects treatment and health outcomes, and increases treatment dropout. This study aimed to examine correlates of concurrent illicit drug use among OAT patients in Ukraine. A random sample of 434 patients currently on OAT receiving buprenorphine (BMT) or methadone maintenance treatment (MMT) from five cities in Ukraine were assessed for factors associated with self-reported concurrent illicit drug use during OAT using a multivariable logistic regression. Among 434 OAT patients, 100 (23%) reported concurrent drug injecting in the previous 30 days; 28% of these were injecting ≥20 days. While 100 (100%) of these injected opioids, 24 (24%) injected stimulants; 40 (40%) met criteria for polysubstance use disorder that included opioids, stimulants and alcohol. Independent correlates of concurrent drug injection included: being on MMT vs. BMT (aOR = 2.8, 95%CI = 1.4-5.8), lower OAT dosage (aOR = 1.7, 95%CI = 1.1-2.7), more severe addiction severity (aOR = 2.3, 95%CI = 1.4-3.8), younger age of injection initiation (aOR = 2.3, 95%CI = 1.3-3.9), and presence of alcohol use disorder (aOR = 2.1, 95%CI = 1.3-3.5); participants living with parents were negatively associated with concurrent drug injection. Concurrent drug use was prevalent among OAT patients in Ukraine indicating the urgent needs for tailored interventions and changes in OAT program design and implementation. Results highlight the importance of prescribing an adequate OAT dosage, and discrepancies between MMT and BMT programs in Ukraine addressing needs of OAT patients with specific characteristics such as severe opioid and alcohol dependence.

Hoang T, Nguyen H, Shiraishi RW, Nguyen M, Bingham T, Nguyen D, Nguyen T, Duong H, Lyss S, Tran H. Factors associated with concurrent heroin use among patients on methadone maintenance treatment in Vietnam: A 24-month retrospective analysis of a nationally representative sample. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2018; 55:113-120. [PMID: 29550740 DOI: 10.1016/j.drugpo.2018.02.020] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2017] [Revised: 02/02/2018] [Accepted: 02/16/2018] [Indexed: 01/13/2023]
Abstract
BACKGROUND Methadone maintenance treatment (MMT) is highly effective for reducing heroin use and HIV transmission among people who inject opioids. We sought to measure and understand factors associated with continued heroin use, a critical factor affecting treatment outcome among MMT patients in Vietnam. METHOD We collected data from medical charts of a nationally representative sample of patients who were on MMT from May 2008 to December 2013. We selected 10 MMT clinics using probability proportional to size and 50 patients/clinic by systematic random sampling. Concurrent heroin use was defined by self-report/positive urine test recorded in patient charts during month 3, 6, 12, and 24 after MMT initiation. We used multivariable logistic regression to identify factors associated with concurrent heroin use over the first 24 months in treatment. FINDINGS All clients used heroin at baseline; concurrent heroin use was 55% at month 3; 19%, 14.6% and 15.2% at month 6, 12, and 24, respectively. Having no family emotional/financial support at baseline versus having this support (AOR = 2.03; 95% confidence interval [CI] = 1.17-3.53); using heroin for <15 years versus ≥15 years at baseline (AOR = 1.55; 95% CI = 1.01-2.38); being HIV-infected/not on antiretroviral treatment (ART; AOR = 1.79; 95% CI = 1.07-2.98) or being HIV infected/on ART (AOR = 2.39; 95% CI = 1.61-3.55), versus not being HIV infected; baseline methamphetamine use versus non-use (AOR = 2.68; 95% CI = 1.08-6.65), were associated with increased odds of concurrent heroin use among patients. CONCLUSION The association between concurrent heroin use among MMT patients and lack of family emotional/financial support, highlights the critical importance of these types of support for successful treatment. Association with shorter heroin use history suggests motivational enhancement may reduce concurrent heroin use. Living with HIV, whether on ART or not, is associated with increased concurrent heroin use and suggests safe injection commodities and education, and drug-drug interaction management, are needed for this subgroup. Though few MMT clients reported baseline methamphetamine use, its association with later heroin use suggests the need for effective methamphetamine use interventions.

Risk behaviour determinants among people who inject drugs in Stockholm, Sweden over a 10-year period, from 2002 to 2012. Harm Reduct J 2017; 14:57. [PMID: 28814336 PMCID: PMC5559856 DOI: 10.1186/s12954-017-0184-8] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2017] [Accepted: 08/09/2017] [Indexed: 01/11/2023] Open
Abstract
BACKGROUND People who inject drugs (PWID) frequently engage in injection risk behaviours exposing them to blood-borne infections. Understanding the underlying causes that drive various types and levels of risk behaviours is important to better target preventive interventions. METHODS A total of 2150 PWID in Swedish remand prisons were interviewed between 2002 and 2012. Questions on socio-demographic and drug-related variables were asked in relation to the following outcomes: Having shared injection drug solution and having lent out or having received already used drug injection equipment within a 12 month recall period. RESULTS Women shared solutions more than men (odds ratio (OR) 1.51, 95% confidence interval (CI) 1.03; 2.21). Those who had begun to inject drugs before age 17 had a higher risk (OR 1.43, 95% CI 0.99; 2.08) of having received used equipment compared to 17-19 year olds. Amphetamine-injectors shared solutions more than those injecting heroin (OR 2.43, 95% CI 1.64; 3.62). A housing contract lowered the risk of unsafe injection by 37-59% compared to being homeless. CONCLUSIONS Women, early drug debut, amphetamine users and homeless people had a significantly higher level of injection risk behaviour and need special attention and tailored prevention to successfully combat hepatitis C and HIV transmission among PWID.

[PMID: 28343774 DOI: 10.1016/j.vaccine.2017.03.034] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2017] [Revised: 03/10/2017] [Accepted: 03/10/2017] [Indexed: 12/16/2022]
Abstract
BACKGROUND AND AIMS To explore whether the immunization with high-dose (60μg) hepatitis B vaccines in patients receiving methadone maintenance treatment (MMT) could yield a superior protection against hepatitis B infection than did the standard dose (20μg). METHODS We conducted a randomized, double-blinded, parallel-controlled trial in MMT patients. Patients with serologically negative hepatitis B surface antigen (HBsAg) and hepatitis B surface antibody (anti-HBs) were randomized in a ratio of 1:1 to receive three intramuscular injections of 20μg or 60μg recombinant hepatitis B vaccine at months 0, 1, and 6. Serum HBsAg and anti-HBs were measured at months 7 and 12 post-vaccination to assess the immunogenicity. RESULTS A total of 196 MMT patients were randomized and 195 received at least one injection (98 and 97 in 20 and 60μg vaccine groups, respectively). The 60μg vaccine group showed a seroconversion of anti-HBs of 87.3%, high-level response rate of 56.3%, and GMC of 742.9mIU/mL at month 7. While these results were numerically higher than the 20μg group, a statistical difference was not found. HIV infection and concomitant drug abuse were negatively associated with the robust immune responses. 7.7% of MMT patients receiving at least one dose of vaccine reported solicited adverse reactions within 7days after vaccination, 2.6% reported unsolicited adverse reactions within 28days after vaccination. None of the MMT patients reported serious adverse events or became HBsAg positive during the follow-up. CONCLUSIONS The three-dose regimen of 60μg recombinant hepatitis B vaccine at months 0, 1, and 6 can yield a similar immunogenicity among MMT patients as compared to the 20μg vaccine.

Abstract
OBJECTIVE We sought to explore the experiences of drug users in China who were recently diagnosed with HIV infection while engaged in methadone maintenance treatment (MMT) and to better understand their perceptions of MMT, HIV risk, and HIV prevention. METHODS We recruited clients of MMT clinics in Chongqing and Kunming who had a baseline HIV-negative test result upon entry to MMT and had been diagnosed with HIV within the past 12 months. We conducted semi-structured qualitative interviews and thematic data analysis to identify situations and factors that increased HIV risk. RESULTS Among the 27 participants who were interviewed, 15 believed their infection was due to injection drug use, 7 attributed their infection to sexual contact, and 5 were unsure as to how they became infected. High risk behaviors were common; 18 participants continued to use drugs during treatment, and 10 engaged in unprotected sex. Common themes were the difficulty of drug abstinence despite receiving MMT, social pressure to continue using drugs, and low knowledge of effective HIV prevention measures. CONCLUSION While MMT is effective in reducing drug usage and needle sharing, many clients remain at risk of HIV infection due to continued injection drug use and unprotected sex. Clients may benefit from additional counseling on HIV prevention methods as well as structural interventions to increase the availability of clean injection equipment.

Abstract
Injection drug users (IDUs) are at high risk of acquiring HIV infection through preventable drug- and sex-related HIV risk behaviors. In recent decade, there has been a growing evidence that methadone maintenance treatment (MMT) is associated with a significant decrease in both drug- and sex-related risk behaviors among this high-risk population. The better understanding of the relationship between MMT and HIV-related risk behaviors will help to better inform future HIV prevention strategies, which may have policy implications as well. In this systematic review, we therefore aimed to explore the relevant literature to more clearly examine the possible impact of MMT on HIV risks behaviors among high-risk IDUs. The findings thus far suggest that MMT is associated with a significant decrease in injecting drug use and sharing of injecting equipment. Evidence on sex-related risk behavior is limited, but suggest that MMT is associated with a lower incidence of multiple sex partners and unprotected sex. The literature also suggests that the most significant factor in reducing HIV risks was treatment adherence. As such, more attention needs to be given in future studies to ensure the higher rates of access to MMT as well as to improve the adherence to MMT.

Abstract
Objective Methadone maintenance treatment (MMT) was introduced to China in 2004 to reduce the harm of injecting drug users (IDUs). However, little is known about continued drug use, especially methamphetamine (MAMP), among MMT patients. Methods A survey was conducted among patients attending five major MMT clinics in Dehong Prefecture in 2014 to investigate the heroin and MAMP use and their associated risk factors. Participants were administered with face-to-face interviews, and urine tests for morphine and MAMP. Results A total of 2,121 were eligible and participated in the study. Among them, 220 (10.4%) were only positive for morphine, 12.9% were only positive for MAMP, and 196 (9.2%) were positive for both morphine and MAMP. Compared with neither use of heroin nor MAMP during MMT, heroin use (not using MAMP) was associated with ethnicity, shorter duration of MMT, lower dose of methadone, and having had no more than two sex partners in the past year; MAMP use (not using heroin) was associated with ethnicity, longer duration of MMT, higher dose of methadone and being aged <30 years (vs. ≥50 years); use of both heroin and MAMP was associated with being Dai minority (vs. Han), a marital status of divorced or widowed, having used drugs for ≥10 years and shorter duration of MMT. Conclusion These findings indicate the complexity in the treatment of heroin users and underscore the importance in prescribing appropriate methadone dosages in order to reduce both heroin and MAMP use.

Abstract
Background Women who use drugs are extremely vulnerable to HIV and sexually transmitted infections (STIs), but studies on risk behaviours and HIV infection among female drug users are limited in Nepal. Methods In this cross-sectional study conducted between September 2010 and May 2011, HIV prevalence and risk factors for HIV infection were investigated among female drug users recruited in drop-in centres, parks and streets in the Kathmandu Valley. The participants completed face-to-face interviews for a structured questionnaire, HIV pre-test counselling, specimen collection for HIV test and they were provided with their results at post-test counselling. Results A total of 269 female drug users were recruited, of whom 28% (n = 77) were found HIV positive; the majority (78%, n = 211) being injecting drug users and aged below 25 years (57%, n = 155). Nearly half (n = 137) of the total participants had shared needles or syringes in the past month, and 131 and 102 participants were involved in commercial or casual sex respectively with only half or less of them having had used condoms in the last 12 months. In multivariate analysis the variables associated with HIV infection included: (a) older age; (b) history of school attendance; (c) frequency of sharing of injection instruments; and (d) unsafe sex with commercial or casual partners. Conclusions HIV was highly prevalent among female drug users in the Kathmandu Valley, with its risk being strongly associated not only with unsafe injection practice but also with unsafe sexual behaviours. Awareness raising programmes and preventive measures such as condom distribution, needle or syringe exchange or methadone maintenance therapy should be urgently introduced in this neglected subpopulation.
